Exhaust manifold kit for Jeep Grand Cherokee 5.7 from 2011 to 2021

Unfortunately, cracked and leaking exhaust manifolds are not uncommon on Jeep Grand Cherokees. Achieve greater durability with the improved exhaust manifold kit designed specifically for 5.7L HEMI engines.
BD Upgrade headers address common header bolt problems by using extended fasteners and spacers that effectively resist thermal expansion.
Cracks in the manifold that also occur frequently are counteracted by a thicker wall, which - in contrast to the OEM manifolds - is evenly thick in all places.
Additionally, independent mounting points were designed for the heat shield to separate it from the mounting bolts and further improve reliability.
Manufactured with high precision, the BD headers feature a robust, thick-walled design and are made from high-silicon ductile iron to counteract deformation and ensure your vehicle remains in top shape over the long term.
